UNITED STATES PATENT OFFICE.

JAMES E. WOODRUFF, OF BUFFALO, NEW YORK, ASSIGNOR OF ONE-HALF HIS RIGHT TO JAMES F. ROWLEY, OF SAME PLAGE.

IMPROVEMENT IN PORTABLE STEAM-GENERATORS.

Specification forming part of Letters Patent N0. 112,76l, dated March 14, 1871; antedated March 6, 1871.

To all whom t't may concern:

Be it known that I, JAMES E. WOODRUFF, ot' Buffalo, in the county of Erie and State ot' New York,have invented a new and useful Improvement in Portable Steam-Generators, ofl which the following is a specicaton.

vlugs e-e, is ineased vWithin the cylinder A, and

serves asa fire-box, C. The two cylinders A and B are securely riveted together through their flanges c and d, the flange d entirely co vering the iiange c, and held in a position in front by the ilanges c and d, and in rear by the lugs c e, to producethe space D. The tire-box Gis provided with the grate E, extending the full length, and also the diaphragm P, having in it an opening near the rear ofthe tire-box, so as to form a return flue, the smoke passing out through the stack G at the front of the generator..

H is the door of the tire-box. I is the safetyvalve; K anescape-pipe, and L a valve for supplying water to the generator. 0 is an opening in rear of generator for cleaning out the water-space D. N is a water cock in the bottom of the generator for drawing oft1 the water. Q is a removable hinged ash-pan secured to the front ofthe generator, so that it will turn up against the end ofthe cylinder and be out the way, and when in use is supported by hinged legs R S and legs of the generator.

There is less expense in constructing my steam-generator than is required in other forms in use, as the furnace and tlue are formed With but asingle steam and water tight cylinder, B, and there is but a single aperture to be made in cylinder A to insert the furnace and lue."

What l claim as my invention, and desire to secure by Letters Patent, is-

1. The oval-shaped cylinder A, having the oval-shaped lire-box B,provided with a diaphragni, P, and surrounded by the water-space D, all constructed and arranged as herein described, and for the purpose specified.

2. In combination with the above, the hinged ash-pan Q, for the purpose specified.

JAS. E. WOODRUFF.
